DESCRIPTION

This module uses a file based database. This database simply contains IP blocks as keys, and countries as values. This database should be more complete and accurate than reverse DNS lookups.

This module can be used to automatically select the geographically closest mirror, to analyze your web server logs to determine the countries of your visiters, for credit card fraud detection, and for software export controls.

To find a country for an IP address, this module a Network that contains the IP address, then returns the country the Network is assigned to.

CLASS METHODS

$gi = Geo::IP->new( $flags );

Constructs a new Geo::IP object with the default database located inside your system's datadir, typically /usr/local/share/GeoIP/GeoIP.dat.

Flags can be set to either GEOIP_STANDARD, or for faster performance (at a cost of using more memory), GEOIP_MEMORY_CACHE.

$gi = Geo::IP->open( $database_filename, $flags );

Constructs a new Geo::IP object with the database located at $database_filename.
